Course Contents
In this course, structural health monitoring is taught, considering modern concepts of data acquisition, data storage and data analysis. Commonly used monitoring techniques, data acquisition systems and transducer types, non-destructive testing and determination of critical measurement types and locations are discussed. In this respect, fundamentals of intelligent sensors and embedded computing autonomous software and decentralized data processing will be illuminated. Furthermore, measuring principles, data acquisition systems, data management and data analysis algorithms are discussed. Structural health monitoring application examples will be demonstrated with advantageous of assessing the condition of structural systems. In further steps, life-time detection of civil engineering structures as a project work is included in this course.
